Gasoline and diesel lines were replaced and impacted <br /> soil was excavated and disposed of off site. Five groundwater monitoring wells were drilled to <br /> w help provide information regarding groundwater quality and hydraulic conditions beneath the <br /> site. Groundwater was encountered during drilling activities at the site at depths ranging from <br /> _ 1.5 to 3 feet below grade. li_aboratoiy analysis of soil samples collected from each monitoring <br /> well determined that petroleum hydrocarbons were detected only in well MW2. Monitoring well <br /> MW2 contained toluene and total xylenes in concentrations of 0,014 mg/kg and 0.027 mg/kg, <br /> respectively. Groundwater samples were collected from each monitoring well on site. Elevated <br /> concentrations of petroleum hydrocarbons were detected only in monitoring wells MW4 and in <br /> MW5 which is located in the approximate location of the diesel 'eak. <br /> King I.L nd R..ort•387 <br /> Rae�sa�.wa 7 <br />
